Abstract (en)
A control device (211) inputs reliability information on the same data block a plurality of times into a reliability storage memory (202). A reliability generating device (201) generates anew reliability information by performing computation processing based on a stochastic computation by using reliability information generated in the previous cycle that has been saved in the reliability storage memory (202) and reliability information generated in the present cycle, and saves the reliability information generated anew in the reliability storage memory (202) when the decoding is performed by using reliability information on the data block same as that in the previous cycle. A column processing computation device (204) computes a column processing output value by using the reliability information generated anew and saved in the reliability storage memory (202) and a row processing output value.
